Try extrudedmesh.forceSharedVertices()

I checked my contour and path generation . removing duplicated points.
Using forceSharedVertices() look worst

Would you put the extrude shape in a PG to make it easier to see what’s going on.

Not sure what you want to do with the normals.

Assuming it is the caps you have an issue with. Suggest you try removing caps, create new ends using Irregular Polygons | Babylon.js Documentation and merge with open extrusion.
